Sorry for the long break. It was very much needed for me though. To make it up, here’s a new type for you to chew on.

I’m not sure I “proved” a darn thing, but I managed to solve it intuitively.

• MellowMelon Says:

That’s alright, especially for a puzzle like this one. I think the intuitive approach is going to be a very bad idea on the next one of these (which is already lined up).

A lovely little puzzle. I look forward to seeing some more testing examples. Congrats.

3. Tyler Says:

I eyeballed it at the very end, but before that I found it crucial to deduce segments’ orientation from the surrounding segments or other edges. Nice one.

I have not tried it yet, just read the rules. The point that is unstated, but I think should be, is that there is a direction to the closed loop, yet there are no arrows indicating direction in your example.

• MellowMelon Says:

Yes, the lack of arrows is a bit of a limitation on the drawing facilities that I may try to remedy soon. I tried to point the direction issue out with the word “oriented” describing the closed loop in the main description; it’s now emphasized a bit more.

Interesting. I’m not sure if you meant it this way, but I solved this one a lot like I would a numberlink–meaning a lot more gut feeling and fewer well-defined progressions of steps. I’d say I used numberlink logic on about half the puzzle.

Oh and welcome back: to blogs and to campus!

Nice idea, nice puzzle. I didn’t do a lot of counting to find what connected, mostly what didn’t connect. I think I counted to 1.

• Jack Says:

Well, for me the main “counting” thing was counting up the squares in the big middle area to verify that absolutely none of the larger regions could re-enter the region.

• MellowMelon Says:

All the cells in the big room? What about summing the given numbers and noticing each number N is in a room of size N? (this was the intent)

• rob Says:

I think I solved it logically without much summing up, but rather local deductions about where the loop could go.

Looking forward to the next in the series!

Enjoyable new diversion. Took me longer than it should have. Starting to develop the tool kit to solve them. I look forward to the next few.

Thanks.

Ah, once I did the summing and realized what needed to happen, it felt more like a proper Monday or Tuesday puzzle. Looking forward to the next one.
